Let's divide 576082 by 77
The aim is to understand the frequency of 77 in 576082.

Going ahead to step 1:
If we divide 5 by 77, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 77

Going ahead to step 2:
57 divided by 77 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (6) from the dividend, attach it to 57 and continue: 576 / 77

Advancing to step 3:
The number 77 fits into 576 7 times, leaving a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 37 after subtracting 539 from 576.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 77

Moving on to step 4:
77 goes into 370 4 times with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we take 308 away from 370, we end up with 62.
Include the next digit (8) from the dividend after 62, then repeat: 628 / 77

Advancing to step 5:
When dividing 628 by 77, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 748.0
Subtracting 616 from 628 leaves us with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 77

Advancing to step 6:
77 goes into 122 1 times with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 7481.0
If we take 77 away from 122, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
The number 77 fits into 450 5 times, leaving a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 7481.5
If we take 385 away from 450, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 8:
The number 77 fits into 650 8 times, leaving a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 7481.58
The remainder is 34 after subtracting 616 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
77 goes into 340 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 7481.584
If we subtract 308 from 340, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
320 divided by 77 is 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 7481.5844
Deduct 308 from 320 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 7481.5844, and the remainder is 0.00012.
